Suggests the relative importance of the mediating and rhetorical roles of verbal language whch may be associated with nonverbal information in multimedia instructional materials, and looks to an interactional model such as Burke's pentad for an explanation of the hortatory nature of interactional communication. Thirteen references are listed.…

Single word and continuous association test behaviors of children (mean age 15.1 years) at high (N=207) and low (N=104) risk for schizophrenia were analyzed as part of a longitudinal prospective study. (SBH)

A study of seven adults with mild mental retardation investigated whether nonverbal behavior was under the control of covert rules and whether verbal reports of these rules were functionally equivalent to the covert rules that control nonverbal behavior. Results indicated self-instructions, when used as external instructions, produced the desired…

Children affected by dyslexia exhibit a deficit in the categorical perception of speech sounds, characterized by both poorer discrimination of between-category differences and by better discrimination of within-category differences, compared to normal readers. These categorical perception anomalies might be at the origin of dyslexia, by hampering…

In three experiments, 18-month-olds were tested in a deferred imitation paradigm. Some infants received verbal information during the demonstration and at the time of the test (full narration), and some did not (empty narration). When tested after a 4-week delay, infants given full narration exhibited superior retention relative to infants given…

Conditional directives are used by speakers to instruct hearers which actions are to be taken should certain events occur. The authors demonstrate that conditional directives are distinct from indicative conditionals in which speakers predict what is likely to be observed should certain events occur. The 1st set of experiments shows that goal…

According to Skinner's (1957) analysis of verbal behavior, the mand and the tact are functionally independent verbal operants, each of which is acquired through a unique history of reinforcement. The present study attempted to replicate the findings of Lamarre and Holland (1985), who empirically demonstrated functional independence of mands and…

Pseudoword (non-word) reading tasks are a commonly used measure of phonological processing across diverse fields of reading research. However, whether pseudoword reading gives any more information about phonological processing in young learner readers than does the reading of real words has seldom been considered. Here we show that pseudoword and…

This study investigated the research construct of encoding specificity using an applied research orientation. Encoding specificity considers the effects on memory of the interactive relationship among encoding, the stored memory trace, and external retrieval cues. Subjects were 273 undergraduate students enrolled in the College of Engineering at…

Problems in the experimental laboratory in scientific research are discussed and solutions are proposed for the problem of conflicts between the experimental model and reality. As a possible beginning for change, an apparatus is suggested to replace the tachistoscope. (SCC)

Male infant vocalizations were studied as a function of age. (JMB)

The ways in which fathers and mothers communicate with and teach their 6-month-old first-born infants were compared. Twenty-two white, middle class mothers and fathers were videotaped interacting with their infants (11 male, 11 female) on 10 tasks. Trained observers coded the parents' interaction with their infants on the following variables:…

A paired-associate task relational or non-relational visual and linguistic stimuli was presented to kindergarten and fifth-grade students. Results indicated that a relationship in both modes facilitated recall better than a relationship in only one mode, and that a relationship in either mode was better for recall than none at all. (DP)
